CAUTIONS FOR SAFETY
i
i
For the sewing machine, automatic machine and ancillary devices (hereinafter collectively referred to as
"machine"), it is inevitable to conduct sewing work near moving parts of the machine. This means that there
is always a possibility of unintentionally coming in contact with the moving parts. Operators who actually
operate the machine and maintenance personnel who are involved in maintenance and repair of the machine
are strongly recommended to carefully read to fully understand the following SAFETY PRECAUTIONS
before using/maintaining the machine. The content of the SAFETY PRECAUTIONS includes items which
are not contained in the specications of your product.
The risk indications are classied into the following three different categories to help understand the meaning
of the labels. Be sure to fully understand the following description and strictly observe the instructions.

v
Precautions to be taken so as to use the LU-2800 Series more safely
1. To ensure safety, never operate the machine with the ground wire for the power
supply removed.
2. When inserting/removing the power plug, the power switch has to be turned OFF in
advance.
3. In time of thunder and lightening, stop your work and disconnect the power plug
from the receptacle so as to ensure safety.
4. If the machine is suddenly moved from a cold place to a warm place, dew conden-
sation may be observed. In this case, turn ON the power to the machine after you
have conrmed that there is no danger of water drops in the machine.
5. To prevent res, periodically draw out the power plug from the plug socket and
clean the root of the pins and the space between pins.
6. The hook rotates at a high speed while the machine is in operation.
To prevent possible injury to hands, be sure to keep your hands away from the vi-
cinity of the hook during operation. In addition, be sure to turn OFF the power to the
machine when replacing the bobbin.
7. To avoid possible accidents due to abrupt start of the machine, be sure to turn OFF
the power to the machine.
8. Be careful of handling this product so as not to pour water or oil, shock by drop-
ping, and the like since this product is a precision instrument.
9. When tilting or returning the sewing machine to the home position, hold the upper
side of the machine head with both hands and perform the work quietly so that n-
gers or the like are not caught in the machine.
1. Keep your hands away from needle when you turn ON the power switch or while the
machine is in operation.
2. Do not put your ngers into the thread take-up cover while the machine is operating.
3. Turn OFF the power switch when tilting the machine head, or removing the belt cov-
er or the V belts.
4. During operation, be careful not to allow your or any other person’s head, hands or
clothes to come close to the handwheel, V belt and motor. Also, do not place any-
thing close to them.
5. Do not operate your machine with the belt cover and nger guard removed.
6. To avoid personal injury, be careful not to allow your ngers in the machine when
tilting the machine head.
BEFORE OPERATION
• Before you put the machine into operation for the rst time after the set-up, clean it thoroughly.
Remove all dust gathering during transportation and oil it well.
• Conrm that voltage has been correctly set.
Conrm that the power plug has been properly connected to the power supply.
• Never use the machine in the state where the voltage type is different from the designated one.
•
The direction of normal rotation of the machine is counterclockwise as observed from the pulley side.
Take care not to allow the machine to rotate in the reverse direction.
• Never operate the machine unless the machine head and the oil tank have been lled with oil.
• For a test run, remove the bobbin and the needle thread.
•
For the rst month, decrease the sewing speed and run the sewing machine at a speed of 80% or less of
the maximum sewing speed. As to the maximum sewing speed, see "6. SEWING SPEED TABLE" p.37.
• Operate the handwheel after the machine has totally stopped.
CAUTION :
Check the following so as to prevent maloperation of and damage to the machine.
